Help with ADE XL simulation

Hi Mingqiang,

First of all, asking this in the Feedback, Suggestions, and Questions forum (which is for issues with the forum itself, not for technical questions) is not the best place to get your question heard and answered. So I moved it into the Custom IC Design forum instead which is more appropriate.

That message is nothing to do with licensing. As far as I can tell, it only happens when you try to copy any variables from the cellView (Right Mouse->Copy from CellView over the Design Variables in the Data assistant for the test, or using the Variables->Copy from Cellview menu in the ADE XL test editor), and then it will only be if it can't find any variables used on the schematic or saved with the schematic. That's not necessarily a problem - it just said there were no variables used.

Regards,

Andrew.

Hello Mr. Andrew,

Sorry for troubling you again!

Latter when I started the simulation, I used the calculator in the ADE XL text editor. 

I selected "cross" function in the calculator and applied it to the output of my variables on the schematic.

When simulating, I did not find out any waveform graphs at the calculator output side. 

Is this because calculator is simply a function that gives voltage or time information? 

Could you please kindly help me with this at your convenience?

Thank you very much!

Best Wishes,

Mingqiang

Unfortunately I don't know what you mean by  you mean by "applied it to the output of my variables on the schematic" or "I did not find out any waveform graphs at the calculator output side". So I have no idea how to answer your question because I what you're asking doesn't make sense...

Perhaps you should speak to your supervisor at your institution?

Hi Andrew,

Maybe I put it in a simple way, may I ask what does the calculator in the text editor do.

Is it used for graph plot or for the data calculation?

Thank you!

I don't know what you mean by "calculator in the text editor", but assuming you're talking about the calculator which is part of ViVA (the waveform tool) and can be accessed by ADE, then this can perform calculations on numbers, waveforms (which have x and y vectors, e.g. representing a voltage or current versus time, or versus frequency, or sometimes versus a swept parameter such as in a DC sweep), or families of waveforms (e.g. if you did a sweep over corners of a transient run in ADE XL), and produce numbers, other waveforms, or families of data. Some of the functions will reduce the dimension of the data (so the cross function when applied to a waveform will return a scalar value; when applied to a single family of waveforms, it would return a waveform of the scalar values versus the swept variable).

You can then use the expressions that the calculator produces as outputs in ADE, or you can plot directly from the calculator.

Regards,

Andrew.

Yes! This is exactly what I want to know about the calculator in the waveform tool. (Sorry for misusing words, I just learnt Cadence on my own.)

If, as you said, the cross function only returns scalar values against swept variables when I applied it on the waveform, then my simulation makes sense.

Thank you very much for your patient answer!

Best Wishes
